  <!-- 
    1. 结构相关
      el-row表示一行，一行分成24份 
       el-col表示列  
       (1) :span="12"  代表在一行中，占12份 (50%)
       (2) :span="6"   表示在一行中，占6份  (25%)
       (3) :offset="3" 代表在一行中，左侧margin份数

       el-form 整个表单组件
       el-form-item 表单的一行 （一个表单域）
       el-input 表单元素（输入框）
    2. 校验相关
       (1) el-form => :model="ruleForm"      绑定的整个form的数据对象 { xxx, xxx, xxx }
       (2) el-form => :rules="rules"         绑定的整个rules规则对象  { xxx, xxx, xxx }
       (3) 表单元素 => v-model="ruleForm.xxx" 给表单元素，绑定form的子属性
       (4) el-form-item => prop配置生效的是哪个校验规则 (和rules中的字段要对应)
